The inhomogeneous mineral content and its topographical distribution on a microscopic scale are major determinants of the mechanical quality of trabecular bone. The kinetics of bone tissue deposition and resorption together with the kinetics of the mineralization process determine the distribution of mineral in the tissue. The heterogeneity of the mineral content is described by the well-established bone mineralization density distribution (BMDD), which is experimentally accessible, e.g., using quantitative electron backscattering imaging (qBEI). In the present work, we demonstrate that the shape of the BMDD histogram of trabecular bone reflects directly the mineralization kinetics. Based on the experimental BMDD data of trabecular bone from healthy human adults and using a mathematical model for the remodeling and the mineralization process, the following main results were obtained. The peaked BMDD reflects necessarily a two-phase mineralization process with a fast primary phase and a slow secondary phase where the corresponding time constants differ three orders of magnitude. The obtained mineralization law, which describes the increase in the mineral content in a bone packet as a function of time, provides information not only about the initial mineralization surge, but also about the slow increase afterwards on the time scale of years. In addition to the mineralization kinetics the turnover rate of the remodeling process has a strong influence on the peak position and the shape of the BMDD. The described theoretical framework opens new possibilities for an analysis of experimentally measured BMDDs with respect to changes caused by diseases or treatments. It a] lows addressing whether changes in the BMDD have to be attributed to a variation in the turnover rate which consequently affects the density distribution or to a primary disorder in the mineralization process most likely reflecting alterations of the organic matrix. This is of important clinical interest because it helps to find therapeutic approaches directly targeting the primary etiological defects to correct the patients' BMDD towards normal BMDD.

The interaction of externally applied currents with persistent currents induced by magnetic field in a mesoscopic triangle is investigated. As a consequence of the superposition of these currents, clear voltage rectification effects are observed. We demonstrate that the amplitude of the rectified signal strongly depends on the configurations of the current leads with the lowest signal obtained when the contacts are aligned along a median of the triangle. When the contacts are aligned off centered compared to the geometrical center, the voltage response shows oscillations as a function of the applied field, whose sign can be controlled by shifting the contacts. These results are in full agreement with theoretical predictions for an analogous system consisting of a closed loop with a finite number of identical Josephson junctions. [less ▲]

PURPOSE: Retrospective studies have shown similar survival among patients with acute myeloid leukemia (AML) and myelodysplasia (MDS) after nonmyeloablative compared with myeloablative conditioning. Refined risk stratification is required to design prospective trials. PATIENTS AND METHODS: We stratified outcomes among patients with AML (n = 391) or MDS (n = 186) who received either nonmyeloablative (n = 125) or myeloablative (n = 452) allogeneic hematopoietic cell transplantation (HCT) based on comorbidities, as assessed by a HCT-specific comorbidity index (HCT-CI), as well as disease status. Patients receiving nonmyeloablative conditioning were older, more frequently pretreated, more often received unrelated grafts, and more often had HCT-CI scores of 3 compared with patients who received myeloablative conditioning. RESULTS: Patients with HCT-CI scores of 0 to 2 and either low or high disease risks had probabilities of overall survival at 2 years of 70% and 57% after nonmyeloablative conditioning compared with 78% and 50% after myeloablative conditioning, respectively. Patients with HCT-CI scores of 3 and either low or high disease risks had probabilities of overall survival of 41% and 29% with nonmyeloablative conditioning compared with 45% and 24% with myeloablative regimens, respectively. After adjusting for pretransplantation differences, stratified outcomes were not significantly different among patients receiving nonmyeloablative compared with myeloablative conditioning, with the exception of lessened nonrelapse mortality (hazard ratio, 0.50; P = .05) in the highest risk group. CONCLUSION: Patients with low comorbidity scores could be candidates for prospective randomized trials comparing nonmyeloablative and myeloablative conditioning regardless of disease status. Additional data are required for patients with low-risk diseases and high comorbidity scores. Novel antitumor agents combined with nonmyeloablative HCT should be explored among patients with high comorbidity scores and advanced disease. [less ▲]

Gliomas frequently display constitutive activation of the transcription factor STAT3, a protein that is known to be able to mediate neoplastic transformation. STAT3 regulates genes that play a central role in cellular survival, proliferation, self-renewal, and invasion, and a cohort of STAT3 target genes have been found that are commonly coexpressed in human cancers. Thus, these genes likely subserve the transforming ability of constitutively activated STAT3. To determine whether the coordinated expression of STAT3 target genes is present in a subset of human gliomas, and whether this changes the biology of these tumors in patients, gene expression analysis was performed in four distinct human glioma data sets for which patient survival information was available. Coordinate expression of STAT3 targets was significantly associated with poor patient outcome in each data set. Specifically, patients with tumors displaying high expression of STAT3 targets had a shorter median survival time compared to patients whose tumors had low expression of STAT3 targets. These data suggest that constitutively activated STAT3 in gliomas can alter the biology of these tumors, and that development of targeted STAT3 inhibitors would likely be of particular benefit in treatment of this disease.
